Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden and fails it. It never says whether the tool reads or writes, what artifact is returned, whether state is persisted, or what the 'playbook' output looks like; the only behavioral statement ('no setup, works in any LLM chatbot') is irrelevant to invocation semantics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
